Abstract

The invention relates to a microfluidic chip and a microfluidic system. The microfluidic chip comprises a droplet flow channel, at least two grating regions, a light source and a wavelength detector,wherein grating constants of the at least two grating regions are different and the grating regions are arranged in the length direction of the droplet flow channel; when droplets are absent in the droplet flow channel, the at least two grating regions reflect light with different designated wavelengths, and when the droplets are present in the droplet flow channel, wavelength of light reflected by the grating regions opposite to the positions of the droplets is different from the designated wavelength; the light source is located at the first end of the droplet flow channel in the length direction and is used for providing incident light including the different designated wavelengths; the wavelength detector detects reflected light after the incident light passes through the grating regions when at the first end, and detects transmitted light after the incident light passes through the grating regions when at the second end opposite to the first end. According to the embodiment, detection accuracy of the droplets in the microfluidic chip can be improved, and accurate control of the droplets can be realized.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic chip and a microfluidic system. Background technique [0002] In related technologies, a microfluidic system generally includes a microfluidic chip for realizing specific functions, a microfluidic operation control device, and a control and detection device for signal acquisition. Wherein, the microfluidic operation control device is located outside the microfluidic chip, and may include a microfluidic detection system for detecting liquid parameters, and the liquid parameters may include position, shape, flow velocity, contact angle, and the like. However, with the improvement of detection requirements in the field of biomedicine, the technical solution of using the above-mentioned microfluidic detection system to measure the droplets in the microfluidic chip has been slightly disadvantaged. Contents of the invention [0003] The invention provides a micr...
